ReNU Syndrome UK
Renewing Hope for Every Family Affected by ReNU Syndrome
What is ReNU Syndrome?
A change in the RNU4-2 gene
A single change in this small gene affects how the body builds proteins from instructions in DNA.
One of the most common rare conditions of its kind
Around 100,000 people worldwide are estimated to have ReNU Syndrome — though most are still undiagnosed.
A new diagnosis for many families
ReNU Syndrome was only identified in 2024, so many families lived without answers for years or decades before diagnosis.
Every person with ReNU is different
Common features include developmental delay, low muscle tone, feeding difficulties, and complex needs — but each person’s experience is unique.
